Description

Technical Field

[0001] The invention relates to the technical field related to pipeline crystal cleaning, and in particular to a tunnel drainage pipe self-adaptive crystal blockage dredging and silt suction device. Background Art

[0002] Tunnel drainage pipes in limestone areas can perform a good water drainage function in the early stage of tunnel operation. However, as the operating years increase year by year, tunnels in limestone areas are affected by the hydrodynamic effects of karst water or dissolved liquids, and white crystals gradually accumulate along the inner and outer walls of the tunnel drainage pipes, which greatly reduces the drainage efficiency and drainage effect of the limestone tunnel, and even eventually leads to complete failure of the drainage pipe, affecting the safety and stability of the tunnel lining structure and the surrounding rock behind the lining.

[0003] At present, a mechanical vehicle is used to enter the interior of the pipeline, and then a rotating scraper is used to scrape and clean the crystals on the inner wall of the pipeline. The crystals and sludge that fall down after cleaning are discharged collectively through the mechanical vehicle. Firstly, the scraper cannot adapt to pipelines of different inner diameters, resulting in the inability to offset the inner wall of the pipeline, thereby reducing the cleaning effect of the crystals. In addition, when the scraper is rotating and scraping the crystals on the inner wall of the pipeline, the sewage at the bottom of the pipeline and the crystals splashed down by the scraping will be driven to the inner wall of the pipeline again, resulting in the scraper also splashing and contaminating the inner wall of the pipeline when scraping the crystals down. This will reduce the cleaning effect of the scraper on the inner wall of the pipeline, and the cleaned sewage will gather at the inner bottom again along the pipe wall, reducing the cleaning effect on the bottom of the pipeline, resulting in the crystals remaining at the bottom of the pipeline again.

[0014] Compared with the prior art, the beneficial effects that the present invention can achieve are: 1. In the present invention, through the servo motor in the motion fitting assembly driving the moving block on the fixed screw rod to achieve reciprocating motion under the limitation of the moving rod, the opening plate realizes stable lifting motion under the action of the T-shaped sliding groove and the T-shaped sliding block. The opening plate will drive the traveling wheels and the auxiliary wheels to fit and support the inner wall of the pipeline with different inner diameters. Through the staggered movement of the arc-shaped scraping plate and the movable scraping plate in the scraping and cleaning assembly, the inner wall of the pipeline is initially cleaned and finely cleaned, and at the same time, the secondary pollution of the inner wall of the pipeline by sewage is reduced. The residue pushing assembly cleans the re-aggregated silt and crystals, improving the cleaning effect inside the pipeline.

[0015] 2. In the present invention, the arc-shaped scraper connected to the arc-shaped swing arm on the outer periphery of the rotating column in the scraping and cleaning assembly is used to perform preliminary rotating scraping on the crystals on the inner wall of the pipeline, scraping off the larger and easily cleanable crystals. The drainage holes on the arc-shaped scraper will not drive the sewage at the bottom of the pipeline to the periphery of the inner wall of the pipeline during the rotating movement. The angle of the arc-shaped scraper is adjusted by using the second hinge and the hinge rod, so that the arc-shaped scraper can be adapted to pipelines with different inner diameters for fitting cleaning, improving the cleaning ability.

[0016] 3. In the present invention, the acidic dissolving liquid is sprayed on the periphery of the pipeline through the connecting seat, the arc-shaped spraying seat and the spraying head to dissolve the difficult-to-clean crystals. The movable scraper in the scraping and cleaning assembly is used to perform fine rotating cleaning on the inner wall of the pipeline. The movable scraper is vertically attached to the inner wall of the pipeline, improving the full and thorough cleaning of the crystals on the inner wall of the pipeline. The lifting of the movable rod in the fixed support plate is adjusted by using the rotating disk, the arc-shaped rotating groove and the fixed rotating shaft, and the distance between the movable scraper and the pipeline with different inner diameters is synchronously adjusted, so that the movable scraper can be attached to the inside of the pipeline for cleaning.

[0017] 4. In the present invention, splash prevention is carried out through the waterproof turning plate rotating on the side of the movable scraper in the scraping and cleaning assembly. When the movable scraper rotates and drives the sewage at the bottom of the pipeline, the sewage rotates the waterproof turning plate, so that the rotating sewage will not adhere to the inner wall of the pipeline along with the movable scraper. The waterproof groove of the movable scraper can also reduce the contact with the sewage at the bottom of the pipeline while cleaning the crystals, improving the cleaning effect on the inner wall of the pipeline.

[0018] 5. In the present invention, the stepper motor in the rotating column of the adaptation and fitting assembly drives the movable screw rod to perform a rotating movement. The movable block on the movable bolt rod realizes a reciprocating movement under the limitation of the hinge rod and the movable groove. During the rotation of the rotating disk, the fixed rotating shaft is driven to expand or contract through the arc-shaped rotating groove, so that the movable scraper and the arc-shaped scraper can move in contact with the inner wall of the pipeline, improving the cleaning effect on the crystals on the inner wall of the pipeline.

[0019] 6. In the present invention, the connecting block and the connecting rod of the residue pushing assembly drive the fan-shaped scraper to push the sewage at the bottom of the pipeline, pushing the collected sewage to the position of the silt suction pipe, and the residual sewage is centrally discharged again through the cooperation of the silt suction pump and the silt suction pipe.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The driving box 57 on the front travel seat 55 drives the travel wheel 56 to travel around the inner wall of the pipeline, and the auxiliary wheel 58 on the rear travel seat 55 cooperates with the travel wheel 56 to drive the cleaning shell 10 to travel inside the pipeline.

The moving block 45 drives the moving ring 41 outside the fixed column 40 to move synchronously through the moving rod 46. The moving ring 41 is connected to the limiting bottom plate 50 through the first hinge 47 and the opening rod 42. The expansion plate 53 is pushed up and down. When the moving ring 41 moves toward one end of the spherical front cover 11, the expansion plate 53 on the limiting bottom plate 50 is driven to move downward through the first hinge 47 and the expansion rod 42. When the moving ring 41 moves away from the spherical front cover 11, the expansion plate 53 on the limiting bottom plate 50 is driven to move downward through the first hinge 47 and the expansion rod 42. The expansion plate 53 realizes stable lifting movement under the action of the T-shaped slide groove 51 and the T-shaped slider 52. The expansion plate 53 will drive the walking wheel 56 and the auxiliary wheel 58 to fit and support the inner wall of the pipe with different inner diameters.

[0025] See also Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10, a scraping and cleaning assembly for cleaning the inner wall of the pipeline is arranged outside the rotating column 20. The arc-shaped scraping plate 21 in the scraping and cleaning assembly preliminarily cleans the crystals on the inner wall of the pipeline. The movable scraping plate 22 in the scraping and cleaning assembly is used to fit the inner wall of the pipeline for fine cleaning. The scraping and cleaning assembly further includes an arc-shaped swing arm 23 and a fixed support plate 24. Three groups of arc-shaped swing arms 23 are evenly arranged on the outer periphery of the rotating column 20 at the end far from the spherical front cover 11. The arc-shaped scraping plate 21 is fixedly installed at the top end of the arc-shaped swing arm 23. Three groups of fixed support plates 24 are evenly installed on the outer periphery of the rotating column 20 at the end close to the spherical front cover 11. An activity rod 70 is connected inside the fixed support plate 24 through a limiting strip 71. The movable scraping plate 22 is fixedly installed at the top end of the activity rod 70. And both the arc-shaped scraping plate 21 and the movable scraping plate 22 are in contact and move with the inner wall of the pipeline. A rotating motor 73 is fixedly installed inside the spherical front cover 11. The output end of the rotating motor 73 is connected with a first gear 74 through a rotating shaft. A second gear 75 is fixedly installed at one end of the rotating column 20 located inside the spherical front cover 11. And the second gear 75 is movably meshed with the first gear 74. A plurality of drainage holes 25 are evenly arranged on the arc-shaped scraping plate 21. Waterproof grooves 26 are arranged on both sides of the movable scraping plate 22. A waterproof turning plate 27 is movably connected in the waterproof grooves 26 of the movable scraping plate 22 through a rotating shaft. A plurality of drainage grooves 28 are evenly arranged on the top of the movable scraping plate 22. The arc-shaped swing arms 23 and the fixed support plates 24 are arranged alternately outside the rotating column 20. A plurality of arc-shaped spraying seats 16 with spraying heads 15 are evenly installed around the top of the spherical front cover 11. A connecting seat 17 connected with the arc-shaped spraying seats 16 is installed inside the spherical front cover 11.

[0026] Refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10, the rotation motor 73 inside the spherical front cover 11 drives the first gear 74 to rotate. The first gear 74 meshes with the second gear 75 to drive the rotating column 20 to rotate. The arc-shaped scraping plate 21 connected to the arc-shaped swing arm 23 on the outer periphery of the rotating column 20 initially rotates and scrapes the crystals on the inner wall of the pipeline, scraping off the larger and easily cleanable crystals. The drainage holes 25 on the arc-shaped scraping plate 21 will not drive the sewage at the bottom of the pipeline to the surrounding of the inner wall of the pipeline during the rotation movement. After the initial cleaning of the inner wall of the pipeline, acidic dissolving liquid is sprayed on the surrounding of the pipeline through the connecting seat 17, the arc-shaped spraying seat 16 and the spraying head 15 to dissolve the difficult-to-clean crystals. Then, the inner wall of the pipeline is finely rotated and cleaned by the movable scraping plate 22. The movable scraping plate 22 is vertically attached to the inner wall of the pipeline, improving the full and thorough cleaning of the crystals on the inner wall of the pipeline. The sludge suction pipe 13, the sludge suction pump 12 and the discharge pipe 14 are used to discharge the sewage and the cleaned crystals inside the pipeline. The waterproof turning plate 27 rotating on the side of the movable scraping plate 22 has a certain anti-splash effect. When the movable scraping plate 22 rotates with the sewage at the bottom of the pipeline, the sewage rotates the waterproof turning plate 27, so that the rotated sewage will not adhere to the inner wall of the pipeline along with the movable scraping plate 22. The waterproof groove 26 of the movable scraping plate 22 can also reduce the contact with the sewage at the bottom of the pipeline while cleaning the crystals, effectively preventing the sewage at the bottom of the pipeline from polluting the surrounding of the pipeline.

[0027] Refer to Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , an adaptation and fitting component is arranged inside the rotating column 20. The adaptation and fitting component is used to fit the movable scraping plate 22 and the arc-shaped scraping plate 21 to the inner wall of the pipeline. The sludge suction pump 12 is arranged inside the spherical front cover 11. The input end of the sludge suction pump 12 is connected with the sludge suction pipe 13 located at the bottom of the spherical front cover 11. The output end of the sludge suction pump 12 is fixedly installed with the discharge pipe 14. The adaptation and fitting component includes a movable screw rod 61 and a rotating disk 62 that move inside the rotating column 20. A stepping motor 60 is fixedly installed at one end of the rotating column 20 close to the rotation motor 73. The movable screw rod 61 is fixedly installed at the output end of the stepping motor 60. The movable screw rod 61 is threadedly connected with a movable block 63 at the end far from the rotation motor 73. A hinge rod 65 is movably connected between the movable block 63 and the arc-shaped swing arm 23 through a second hinge 64, and the hinge rod 65 movably penetrates through the movable groove 66 opened in the rotating column 20. The movable screw rod 61 is fixedly installed with a rotating disk 62 at the end close to the rotation motor 73. The rotating disk 62 is provided with an arc-shaped rotating groove 67. The bottom of the movable rod 70 is fixedly installed with a fixed rotating shaft 72 that matches the size of the arc-shaped rotating groove 67, and the fixed rotating shaft 72 moves in the arc-shaped rotating groove 67.

[0028] Refer to Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 By driving the movable screw rod 61 to rotate through the stepper motor 60 inside the rotating column 20, the movable block 63 on the movable bolt rod realizes reciprocating motion under the limitation of the hinge rod 65 and the movable slot 66. During the movement of the movable block 63, the arc swing arm 23 is adjusted in angle through the second hinge 64 and the hinge rod 65, so that the arc scraper 21 at the top of the arc swing arm 23 fits the inner wall of the pipe with different inner diameters. The movable screw rod 61 synchronously drives the rotating disk 62 to rotate. During the rotation of the rotating disk 62, the fixed rotating shaft 72 is driven to expand or contract through the arc-shaped rotating groove 67. When the fixed rotating shaft 72 contracts, the movable rod 70 in the fixed support plate 24 is driven to move downward, and the movable rod 70 synchronously drives the movable scraper 22 at the top to descend. Similarly, when the fixed rotating shaft 72 expands, the movable rod 70 in the fixed support plate 24 is driven to move upward, and the movable rod 70 drives the movable scraper 22 at the top to move upward. In this way, when the angle of the arc swing arm 23 is adjusted, the distance of the movable scraper 22 can also be adjusted, so that the movable scraper 22 and the arc scraper 21 can fit the inner wall of the pipe to improve the cleaning effect of the crystal on the inner wall of the pipe.

[0029] Refer to Figure 1 、 Figure 5 、 Figure 11 and Figure 12 A residue pushing component is arranged at the inner bottom of the cleaning housing 10. The sector-shaped scraper 30 in the residue pushing component scrapes the residue at the bottom of the pipe to the position of the silt suction pipe 13. The residue pushing component further includes a base block 80 fixedly installed at the bottom of the cleaning housing 10. Conical guide rails 81 are fixedly installed on the upper and lower sides of the base block 80. A side plate 85 is connected between the conical guide rails 81 through a connecting block 82. A plurality of base columns 83 are fixedly installed on one side of the base block 80 close to the side plate 85.

The tooth grooves of the active gear 84 are in contact with the base columns 83. During the rotation of the active gear 84, it will move horizontally along the base columns 83.

[0030] Refer to Figure 1 、 Figure 5 、 Figure 11 and Figure 12, a side frame 32 is connected inside the side plate 85 through a limiting groove 31. A support rotating shaft 33 is movably arranged inside the side frame 32. A driving gear 84 is fixedly installed on the support rotating shaft 33. A first bevel gear 34 is installed on the support rotating shaft 33 in the side frame 32. A first motor 35 is installed on the top of the side frame 32. The output end of the first motor 35 is connected through a rotating shaft to a second bevel gear 36 located in the side frame 32, and the second bevel gear 36 is movably meshed with the first bevel gear 34. The first motor 35 drives the second bevel gear 36 to rotate. The second bevel gear 36 meshes with the first bevel gear 34 to drive the support rotating shaft 33 to rotate. The support rotating shaft 33 then drives the driving gear 84 to rotate outside the base column 83. The driving gear 84 moves back and forth while rotating outside the base column 83, driving the side plate 85 and the side frame 32 to move horizontally. The sector-shaped scraper 30 under the side frame 32 pushes the sewage gathered at the bottom. When the driving gear 84 moves to one side of the top of the base column 83, the side frame 32 rises to the top position of the side plate 85, and the sector-shaped scraper 30 is lifted. Then the sector-shaped scraper 30 moves back to its original position during the return stroke. A connecting block 37 is fixedly installed at one end of the side frame 32 away from the base block 80. A connecting rod 38 is fixedly installed at the bottom of the connecting block 37. The sector-shaped scraper 30 is installed at the bottom end of the connecting rod 38.

[0031] Refer to Figure 5 , Figure 11 and Figure 12 , when the side plate 85 moves to both ends of the base block 80, the driving gear 84 flips along the base column 83. The driving gear 84 will enter and move to one side of the top of the base column 83. When it rotates, the side frame 32 will rise in the limiting groove 31 of the side plate 85. When the driving gear 84 moves at the bottom of the base column 83, it drives the sector-shaped scraper 30 to push the sewage at the bottom of the pipeline through the connecting block 37 and the connecting rod 38, and pushes the gathered sewage to the position of the silt suction pipe 13. The residual sewage is centrally discharged again through the cooperation of the silt suction pump 12 and the silt suction pipe 13. When the driving gear 84 flips and moves to the top of the base column 83, the sector-shaped scraper 30 separates from the bottom of the pipeline and drives the sector-shaped scraper 30 to move back to its original position during the return stroke.

[0032] Working principle: The traveling wheels 56 and auxiliary wheels 58 of the traveling seat 55 are attached to the inner wall of the pipeline. The driving box 57 on the front-end traveling seat 55 drives the traveling wheels 56 to travel around the inner wall of the pipeline. The auxiliary wheels 58 on the rear-end traveling seat 55 cooperate with the traveling wheels 56 to drive the cleaning housing 10 to travel inside the pipeline. When cleaning pipelines with different inner diameters, the servo motor 43 drives the moving block 45 on the fixed screw 44 to perform reciprocating motion under the limitation of the moving rod 46. The moving block 45 drives the moving ring 41 outside the fixed column 40 to perform synchronous motion through the moving rod 46. The moving ring 41 pushes the opening plate 53 on the limiting bottom plate 50 to rise and fall through the first hinge 47 and the opening rod 42. When the moving ring 41 moves towards one end of the spherical front cover 11, the opening plate 53 on the limiting bottom plate 50 is driven to move downward through the first hinge 47 and the opening rod 42. When the moving ring 41 moves away from the spherical front cover 11, the opening plate 53 on the limiting bottom plate 50 is driven to move downward through the first hinge 47 and the opening rod 42. The opening plate 53 realizes stable lifting motion under the action of the T-shaped chute 51 and the T-shaped slider 52. The opening plate 53 will drive the traveling wheels 56 and the auxiliary wheels 58 to be attached to and support the inner wall of the pipeline with different inner diameters.

[0033] After the cleaning housing 10 and the spherical front cover 11 enter the pipeline, the rotating motor 73 in the spherical front cover 11 drives the first gear 74 to rotate. The first gear 74 meshes with the second gear 75 to drive the rotating column 20 to rotate. The arc-shaped scraper 21 connected to the arc-shaped swing arm 23 on the outer circumference of the rotating column 20 performs preliminary rotating scraping on the crystals on the inner wall of the pipeline, scraping off the larger and easily cleanable crystals. The drainage holes 25 on the arc-shaped scraper 21 will not drive the sewage at the bottom of the pipeline to the surrounding of the inner wall of the pipeline during the rotating motion. After the preliminary cleaning of the inner wall of the pipeline, acidic dissolving liquid is sprayed on the surrounding of the pipeline through the connecting seat 17, the arc-shaped spraying seat 16 and the spraying head 15 to dissolve the difficult-to-clean crystals. Then, the movable scraper 22 performs fine rotating cleaning on the inner wall of the pipeline. The movable scraper 22 is vertically attached to the inner wall of the pipeline to improve the full and thorough cleaning of the crystals on the inner wall of the pipeline. The sludge suction pipe 13, the sludge suction pump 12 and the discharge pipe 14 are used to discharge the sewage and the cleaned crystals inside the pipeline. When cleaning crystals to adapt to pipes with different inner diameters, the stepping motor 60 inside the rotating column 20 drives the movable screw rod 61 to rotate. The movable block 63 on the movable bolt rod reciprocates under the limitation of the hinge rod 65 and the movable groove 66. During the movement of the movable block 63, the arc swing arm 23 is adjusted in angle through the second hinge 64 and the hinge rod 65, so that the arc-shaped scraping plate 21 at the top of the arc swing arm 23 fits and moves along the inner wall of the pipe with different inner diameters. The movable screw rod 61 synchronously drives the rotating disk 62 to rotate. During the rotation of the rotating disk 62, the fixed rotating shaft 72 is driven to expand or contract through the arc-shaped rotating groove 67. When the fixed rotating shaft 72 contracts, the movable rod 70 in the fixed support plate 24 descends, and the movable rod 70 synchronously drives the movable scraping plate 22 at the top to descend. Similarly, when the fixed rotating shaft 72 expands, the movable rod 70 in the fixed support plate 24 ascends, and the movable rod 70 drives the movable scraping plate 22 at the top to ascend. In this way, when adjusting the angle of the arc swing arm 23, the distance of the movable scraping plate 22 can also be adjusted, so that the movable scraping plate 22 and the arc-shaped scraping plate 21 can fit and move along the inner wall of the pipe, improving the cleaning effect of the crystals on the inner wall of the pipe. After the movable scraping plate 22 rotates to the bottom position of the pipe, a certain degree of splash-proof effect is achieved through the waterproof turning plate 27 that rotates on the side of the movable scraping plate 22. When the movable scraping plate 22 rotates and drives the sewage at the bottom of the pipe, the sewage rotates the waterproof turning plate 27, so that the sewage driven by the rotation will not adhere to the inner wall of the pipe along with the movable scraping plate 22. The waterproof groove 26 of the movable scraping plate 22 can also reduce the contact with the sewage at the bottom of the pipe while cleaning the crystals, effectively preventing the sewage at the bottom of the pipe from polluting the surrounding of the pipe.

[0034] After the silt suction pump 12 discharges the sewage at the bottom of the pipeline and the crystals scraped and cleaned, the movable scraper 22 and the arc-shaped scraper 21 will carry the sewage at the bottom of the pipeline and adhere to the inner wall of the pipeline during the process of cleaning the crystals. At this time, the sewage adhering to the periphery of the pipeline will re-converge to the inner bottom of the pipeline under the action of gravity. At this time, the sewage converged at the inner bottom of the pipeline can be pushed to the bottom position of the silt suction pipe 13 by the sector-shaped scraper 30, and the residual sewage converged at the bottom is discharged again, improving the cleaning effect of the inner wall of the pipeline. Specifically, the first motor 35 on the side frame 32 drives the second bevel gear 36 to rotate. The second bevel gear 36 meshes with the first bevel gear 34 to drive the support rotating shaft 33 to rotate. The support rotating shaft 33 drives the driving gear 84 to mesh with the base column 83. When the driving gear 84 rotates at the bottom side of the base column 83, the tooth grooves of the driving gear 84 will move on the outer periphery of the base column 83. At this time, the driving gear 84 moves along the bottom side of the base column 83. During the movement of the driving gear 84, the side plate 85 and the side frame 32 are driven to move synchronously through the base block 80, the conical guide rail 81 and the connecting block 82. When the side plate 85 moves to both ends of the base block 80, the driving gear 84 flips along the base column 83, and the driving gear 84 will enter the top side of the base column 83 and rotate. When rotating, the side frame 32 will move upward in the limit groove 31 of the side plate 85. When the driving gear 84 moves at the bottom of the base column 83, the sector-shaped scraper 30 is driven through the connecting block 37 and the connecting rod 38 to push the sewage at the inner bottom of the pipeline, and the converged sewage is pushed to the position of the silt suction pipe 13. The residual sewage is concentrated and discharged again through the cooperation of the silt suction pump 12 and the silt suction pipe 13. When the driving gear 84 flips and moves to the top of the base column 83, the sector-shaped scraper 30 is separated from the inner bottom of the pipeline and drives the sector-shaped scraper 30 to return to the original position. The sector-shaped scraper 30 is reset to wait for the next centralized cleaning of the sewage at the inner bottom of the pipeline.

Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
